> You're now arguing about something which isn't even in the proposal from the EU

Yeah. The HN link here is not to the EU proposal. It’s to this dude’s article, which is very clearly what I was responding to.

> I guess to demonstrate to people that this already happens regularly with passports, ID cards, driving licenses etc

No. That’s not what he was doing at all. He very explicitly was not talking about a passport or ID card.

He was describing a physical analog to the digital proposal.

> This sort of solution requires a central issuer/authority to know about the tokens, there's no way round that as there is no way round governments issuing passports if you want border control.

You seem to have completely lost the plot. We aren’t discussing passports. No one is talking about anonymous international travel here.
